Abstract
L'invention concerne un procédé d'égalisation développé pour des environnements de canal de communication sans fil à faible latence et faible largeur de bande. Grâce à ce procédé, une copie exacte, une copie presque exacte, ou un facsimilé d'un message (ou d'informations associées), qui ont été transmis via un canal de communication sans fil à faible latence et faible largeur de bande, sont également envoyés via un canal de communication principal tel qu'un réseau de fibres optiques. Une égalisation est généralement exécutée en comparant le message original reçu, à la copie envoyée via le canal principal. Le message original peut incorporer un retard de canal ajouté pour compenser le retard entre le canal sans fil primaire et le canal principal.
